CLAIMS

1 . A heated and chilled water dispenser comprising:

a housing;

an input port fast with the housing for connection to a mains pressure water supply;

at least one chilled water container arranged to receive water from the input port;

a water chilling assembly arranged to cool said at least one chilled water container;

at least one hot water tank including a heating element and a water receiving arrangement to receive water from the input port, the water receiving arrangement including an inlet valve responsive to water level;

an inlet plenum associated with the inlet valve, the plenum being coupled with the input port to receive water, the plenum further comprising a fill pipe coupled to the hot water tank for supplying water to the hot water tank;

a thermostat coupled to said at least one hot water tank for controlling the heating element and thus temperature of water within the hot water tank;

a two way outlet tap configured for dispensing hot water from the hot water supply or chilled water from the chilled water container in accordance with a user's selection;

a liquid delivery device coupled to said at least one hot water tank for supplying hot water from the hot water tank, said device being arranged to be actuated by the outlet tap.

2. A heated and chilled water dispenser further comprising a steam return line to return steam from the hot water tank to the plenum.

3. A heated and chilled water dispenser in accordance with claim 1 or claim 2 wherein the inlet valve is operated mechanically in response to changes in water level in the tank.

4. A heated and chilled water dispenser in accordance with any one of the preceding claims wherein the inlet valve operates in response to a float-type valve.

5. A heated and chilled water dispenser in accordance with claim 4 wherein the float-type valve is positioned in the plenum.

6. A heated and chilled water dispenser in accordance with any one of the preceding claims wherein the inlet plenum includes a steam release port.

7. A heated and chilled water dispenser in accordance with any one of the preceding claims wherein the fill pipe is metered or configured relative to heating capacity of the hot water tank.

8. A heated and chilled water dispenser in accordance with any one of the preceding claims wherein the liquid delivery device is a pump coupled to the outlet tap, the outlet tap further comprising an actuating arrangement whereby in at least one operable configuration the actuation arrangement actuates the liquid delivery device thereby delivering hot water from the tank to the outlet.

9. A heated and chilled water dispenser in accordance with claim 8 wherein the outlet tap comprises a tap body and a movable handle that is movable between a hot water dispensing open position, a chilled water dispensing open position and a closed position wherein a sensor is mounted in association with said movable handle to detect movement of said handle to the hot water dispensing open position, the sensor being coupled to the actuation arrangement to actuate the liquid delivery device.

10. A heated and chilled water dispenser in accordance with claim 9 wherein the sensor comprises:

a magnetic member mounted to one of the tap body or the movable handle; and

a pin mounted to the other of the tap body or the movable handle;

whereby movement of the handle to the hot water dispensing open position results in contact between the magnetic member and the pin resulting in actuation of the liquid delivery device.

1 1 . A heated and chilled water dispenser in accordance with claim 9 or claim 10 wherein the tap handle is operable to be:

turned in a first direction to the chilled water dispensing open position; and

moved in an orthogonal direction relative to the first direction followed by turning the handle in a second direction to the hot water dispensing open position.

12. A heated and chilled water dispenser according to any one of the preceding claims including a temperature controller for the chilling assembly whereby operation of the chilling controller adjusts the operation of a condenser fan of said assembly.

13. A heated and chilled water dispenser according to claim 12, wherein the housing includes vents formed through at least two of its sides for assisting the fan in cooling the condenser.

14. A heated and chilled water dispenser according to claim 12 or claim 13, wherein the chilling assembly includes a temperature sensor that is coupled to the temperature controller for assisting in maintaining a desired chill temperature.

15. A heated and chilled water dispenser according to any one of the preceding claims, wherein the at least one chilled water container comprises first and second containers that are connected in parallel to a chilled water output port of the dispenser.

16. A dispenser according to any one of the preceding claims, wherein a filter is disposed in piping between the input port and the hot water tank and the at least one chilled water container.

17. A dispenser according claim 16, wherein the housing is formed with a recess in which the filter is located

18. A dispenser according to claim 17, wherein the recess is closed with a hinged cover.

19. A dispenser according to any one of the preceding claims, including controls mounted on a front panel of the housing for on/off power to the unit and for turning the heating element and chilling assembly on and off independently.

20. A dispenser according to any one of the preceding claims wherein the tap is selected to handle water temperatures up to 100 degrees Celsius at standard mains water pressure.

21 . A heated and chilled water dispenser comprising:

a housing;

an input port fast with the housing for connection to a mains pressure water supply;

at least one chilled water container arranged to receive water from the input port;

at least one unvented hot water tank including a heating element and arranged to receive water from the input port;

a water chilling assembly arranged to cool said at least one chilled water container;

a thermostat coupled to said at least one hot water tank for controlling the heating element and thus the water temperature of the tank; and

a two-way outlet tap configured for dispensing mains pressure hot water from the hot water tank or mains pressure chilled water from the chilled water container in accordance with a user's selection.
